Well, using a build directory other than the source directory is  
common practice to either try multiple configurations (e.g., ppc and  
ppc64) or to be able to just `rm -rf' and start from scratch.

git clone git://git.qemu.org/qemu.git
mkdir qemu-something # or mkdir -p qemu/subdir
cd qemu-something
../qemu/configure ... && make
# observe error occurring without my patches
git am ...
# check if any further errors occur with my patches on Linux

During my attempts to get things compiling I did `git submodule init'.

$ git submodule
-d1d6b53b713a2b7c2c25685268fa932d28a4b4c0 roms/SLOF
-7aee315f61aaf1be6d2fff26339f28a1137231a5 roms/ipxe
-cc975646af69f279396d4d5e1379ac6af80ee637 roms/seabios
-19ea12c230ded95928ecaef0db47a82231c2e485 roms/vgabios

roms/{seabios,vgabios}/Makefile were being symlinked in configure, the  
other two not.

If I
$ git submodule update roms/SLOF
I see there is a roms/SLOF/Makefile, too. But at least with my two  
patches in place, SLOF is not being built automatically on Darwin.
David or Ben will be better suited for instructions on how to build  
SLOF. :)
